To tell you the truth, i can't stand ANY of the soaps. It's only coz the wife had it on.
But my ears pricked up (like they do being a Knopfler fanatic)
And like you, i was going shhhhhh shhhhhhhh shhhhhhhhhh, straining to hear EVERY note.
Not the first time Coronation St or Eastenders for that matter has had DS or MK on in the background.
I think Eastenders had 'Boom Like' That on a few years back.
I took the Street tour at Granada Studios about 15 yrs ago. It was GREAT to walk on the cobbles.!
